When applying anhydrous ammonia or ammonia-laden manure, waiting until soil temperatures drop below 50 degrees maximizes nitrogen availability and minimizes its loss.

The other highlights how manure application timing affected yields, effectiveness and nitrate-nitrogen losses through tile lines for four corn-soybean rotations.
